Dr. Sargent has done all my root canals. This latest root canal was an emergency and Dr. Sargent went out of his way to fit me in. All the staff is professional, friendly, and very accommodating. One time he even saw me on a Saturday. I have family in other cities who must wait weeks to be seen by an endodontics dentist. Lubbock is blessed to have such a great doctor. I highly recommend Dr. Sargent. He is the best!!!
